Abstract
The invention discloses a modification and toughening treatment method for a high-molecular composite explosion-proof door panel, a modified and toughened coating raw material liquid used by the method and a preparation method of the modified and toughened coating raw material liquid, wherein the modified and toughened coating raw material liquid is prepared by mixing 10-20% of a toughening modifier, 1-10% of a modification auxiliary agent, 1-5% of a surfactant, 10-20% of a polyester coating and 55-75% of a solvent in percentage by mass. After the modified toughening coating raw material liquid is used for carrying out evaporation coating modification treatment on the high-molecular composite explosion-proof door panel, the toughness and the strength of the high-molecular composite explosion-proof door panel are obviously improved, and the use requirement can be met, so that the high-molecular composite explosion-proof door panel can meet the lightweight requirement and simultaneously achieve the performance of resisting detonation wave impact equivalent to that of the traditional explosion-proof door panel. The modified toughening treatment process is simple to operate, the thickness of the toughened coating on the surface of the composite explosion-proof door panel obtained by treatment is uniform, the performance of different batches of explosion-proof doors is stable, and the requirements of industrial continuous production are completely met.
Description
Technical Field
The invention belongs to the technical field of civil air defense engineering safety, and particularly relates to a modification and toughening treatment method for a high-molecular composite explosion-proof door panel, a modified and toughened coating raw material liquid used by the method, and a preparation method of the modified and toughened coating raw material liquid.
Background
The explosion door is an explosion-proof protection device which can resist explosion impact under certain conditions, dissipate shock wave pressure generated by explosion, absorb fragment impact kinetic energy, prevent penetration and effectively prevent explosion hazards from continuing and avoiding the influence of the explosion waves. The explosion-proof door is widely applied to places such as command rooms, civil air defense projects, explosive storehouses, inflammable goods warehouses, workshops and mines. Especially, the explosion vent used in civil air defense engineering can effectively resist and stop shock waves generated by explosion, and protect the life and property safety of people.
The traditional explosion-proof door plate is usually of a reinforced concrete structure or a steel structure, and the structure has the advantages of firmness and durability, but has the defects of heavy weight, inconvenient use and the like. Patent CN209384979U, for example, discloses a disintegratable vent comprising: the reinforced concrete door comprises a reinforced concrete main door, a reinforced concrete auxiliary door spliced with the reinforced concrete main door, a fixing steel plate for fixing the reinforced concrete main door and the reinforced concrete auxiliary door and playing a role in reinforcement, and bolts for fixing the fixing steel plate to the reinforced concrete main door and the reinforced concrete auxiliary door. In the aspect of door body structure form, the reinforced concrete explosion-proof door adopts more structural forms, mainly adopts a flat plate type, and adopts the internal form of tailor welding of a steel skeleton (steel beam plate) or edge wrapping of section steel and binding and pouring of reinforcing steel barsIn the form of (1). However, the areal density of doors consisting of steel and concrete is greater than 450kg/m3The explosion-proof door is very heavy, so that the operation is very difficult in the installation, use, maintenance and maintenance processes, and the difficulty of opening and closing the explosion-proof door is increased due to the corrosion of steel.
